Hinting that Edwards could have been behind it, the N-Dubz star said that she was made aware of the video's existence six months ago, when a "mutual friend" informed her that Edwards had "been threatening to bring it out to ruin my career".

However, Edwards - who has seen his Twitter following rise several thousand overnight - tweeted; "I believe in silence being a sign of Integrity but in this case I guess I'll have to speak up and Lay out the facts and let you guys decide (sic)."

A number of hours later, he added: "To find the truth both sides of the story should be heard b4 passing judgement #thatisall."

The updates follow a tweet he made on the day the video leaked, in which he stated that it had "nothing to do with me".
